Abstract

Die Erfindung betrifft ein Verfahren zur Herstellung von hochmolekularem, gegebenenfalls verzweigten Polyarylen­ sulfiden aus Alkalisulfiden, gegebenenfalls im Gemisch mit Alkalihydrogensulfiden und Dihalogenaromaten in einem polaren Lösungsmittel, in Gegenwart von 0,1 bis 6,0 Mol-%, bevorzugt 0,25 bis 4,0 Mol-% einer aromati­ schen Monoalkoxy- bzw. Monoalkylthioverbindung. Die so erhaltenen Polyarylensulfide haben reproduzierbar ein­ stellbare Schmelzviskositäten bzw. Molmassen und zeich­ nen sich durch eine geringere Korrosion aus. The invention relates to a method for producing high molecular weight, optionally branched polyarylene sulfides from alkali sulfides, optionally in a mixture with alkali hydrogen sulfides and dihaloaromatic compounds in a polar solvent, in the presence of 0.1 to 6.0 mol%, preferably 0.25 to 4.0 mol% of an aromatic the monoalkoxy or monoalkylthio compound. The so Polyarylene sulfides obtained have a reproducible adjustable melt viscosities or molecular weights and drawing are characterized by less corrosion.
